Finding chemistry solutions in nature (IMAGE) Scripps Research Institute Caption Ben Shen, professor and chair of the Scripps Research Department of Chemistry in Jupiter, Florida, has discovered a new group of enzymes that install sulfur molecules in proteins .A unique resource at the institute, one of the world's largest collections of microbial natural products, made the discovery possible. In biology, sulfur chemistry plays a role in aging and disease, but is difficult to study due to its reactivity. Credit Scott Wiseman for Scripps Research Usage Restrictions No restrictions.
